CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.14/829,817 filed on Aug. 19, 2015, which is a continuation ofInternational Patent Application No. PCT/CN2014/079660 filed on Jun. 11,2014. All of the aforementioned applications are hereby incorporated byreference in their entireties.

TECHNICAL FIELD

The present disclosure relates to communications technologies, and inparticular, to a method for quickly starting an application service, anda terminal.

BACKGROUND

Currently, a smartphone becomes an important communication tool inpeople's life, and quickly making a call anytime anywhere is a basicappeal of person-to-person communication. Currently, for making a callby using a smartphone, the steps usually include selecting a dial-uptool, inputting a number in a dial-up interface, tapping a call button,and then calling out. In addition, the dial-up interface is usuallycombined with an address book. A user may also select a contact from theaddress book, enter a details interface of the contact, and then tap adial-up button to call out. A button-pressing operation of at leastthree steps is required in this dial-up process. If the smartphone is ina screen-off state or a standby state (and a screen lock is set for themobile phone), for making a call, the steps further include lighting upa screen and unlocking the screen. However, because of a limitation of abattery life, a smartphone is in a standby or screen-off state for mosttime. In this case, if the user needs to make a call, a button-pressingoperation with at least five steps is required. Therefore, current stepsfor making a call by using a smartphone are relatively complex and notuser-friendly. Therefore, a realistic user demand to be urgentlyresolved is to implement quickly making of a call on a smartphone by auser by performing fewer button-pressing operations.

To enable a user to quickly make a call on a smartphone, in the priorart, a voice of the user is converted into a text by an application,such as a voice assistant, on the smartphone and by using a speechrecognition technology, so as to become an instruction of a smartphonesystem, that is, a call can be made by means of voice input.

However, in the prior art, for starting a voice application, amicrophone (Mic) needs to be occupied for recording, and if the voiceapplication is used in the case of screen-off, a recording device in abackground needs to perform recording for a long time, and anapplication processor (AP) cannot be on standby for a long time, therebyincreasing power consumption of a smartphone and affecting a batterylife of the smartphone.

Apparently, the describedembodiments are a part rather than all of the embodiments of the presentdisclosure. All other embodiments obtained by persons of ordinary skillin the art based on the embodiments of the present disclosure withoutcreative efforts shall fall within the protection scope of the presentdisclosure.

A terminal, namely, a user equipment, in this application may be awireless terminal or a wired terminal. The wireless terminal may referto a device that provides a user with voice and/or data connectivity, ahandheld device with a radio connection function, or another processingdevice connected to a radio modem. The wireless terminal may communicatewith one or more core networks through a radio access network (RAN). Thewireless terminal may be a mobile terminal, such as a mobile phone (alsoreferred to as a “cellular” phone) and a computer with a mobileterminal, for example, may be a portable, pocket-sized, handheld,computer built-in, or in-vehicle mobile apparatus, which exchanges voiceand/or data with the radio access network. For example, it may be adevice such as a personal communication service (PCS) phone, a cordlesstelephone set, a Session Initiation Protocol (SIP) phone, a wirelesslocal loop (WLL) station, or a personal digital assistant (PDA). Thewireless terminal may also be referred to as a system, a subscriberunit, a subscriber station, a mobile station, a mobile terminal, aremote station, an access point, a remote terminal, an access terminal,a user terminal, a user agent, a user device, or a user equipment.

The technical solutions of the present disclosure may be applicable toany scenario in which a terminal is in a screen-on state, a black screenstate with a running AP, and a black screen state with a standby AP. Ablack screen refers to a screen-off state, that is, a state in which ascreen of the terminal is powered off. Further, in the embodiments ofthe present disclosure, the black screen may further include a screenlocked state that is presented after the screen is lighted up in thescreen-off state, that is, an initial status of the terminal is thescreen-off state, and after a user lights up the screen, the terminal ispresented in a screen locked state. The state of black screen with arunning AP refers to a state in which the terminal is in the screen-offstate, but some applications in a background still run. For example,when the screen of the terminal is off, some instant messaging software(such as WeChat) still runs in the background; in this case, the AP isin a running state. The state of black screen with a standby AP refersto a state in which the terminal is in the screen-off state, and noapplication runs in the background.

FIG. 1 is a schematic flowchart of Embodiment 1 of a method for quicklystarting an application service according to the present disclosure. Asshown in FIG. 1 , the method may include the following steps.

S101. A terminal acquires event trigger information, where the eventtrigger information is used to start application service software on theterminal. When a user needs to quickly start an application service onthe terminal, the user may perform a related trigger operation on theterminal, so that a processing chip inside the terminal can acquire theevent trigger information according to the trigger operation of theuser, and report the event trigger information to an operating system ofthe terminal. Optionally, a related event triggered by the user on theterminal may be a button event (pressing a button only once), and may bea sensor sensing event, such as a gravity sensing event or a speedsensing event. For example, when the user holds down a physical buttonof a smartphone, the smartphone responds to a button event of the user,that is, converts the button event into event trigger information (theevent trigger information may include a signal, data, and the like afterconversion), and reports the event trigger information to an operatingsystem of the smartphone.

S102. The terminal starts the application service software afterdetermining that the event trigger information meets a preset quickstartup condition. After acquiring the event trigger information, theoperating system of the terminal performs encapsulation andclassification processing on the event trigger information, that is, theoperating system of the terminal determines a type of the event triggerinformation, determines, according to the type of the event triggerinformation, a quick startup condition corresponding to the eventtrigger information, and then determines whether the event triggerinformation meets the determined quick startup condition. Optionally,the quick startup condition may be determining whether a time ofacquiring the event trigger information exceeds a preset time threshold,or may be determining whether the type of the event trigger informationmatches information preset in the terminal, or may further be whethercontent included in the event trigger information is the same asinformation preset in the terminal, or may further be anotherdetermining condition. If a result of the determining is that the eventtrigger information meets the quick startup condition, the terminalstarts corresponding application service software. Optionally,performing a different trigger operation by the user can enable theterminal to acquire different event trigger information, and differentevent trigger information is corresponding to different applicationservice software. For example, if the user currently wants to start avoice service, when the user holds down a physical button (such as avolume down button) on the terminal, the event trigger informationobtained by the terminal is information about voice service software.That is, a trigger operation performed by the user, event triggerinformation acquired by the terminal according to the trigger operationperformed by the user, and an application service software that needs tobe started are corresponding to one another. Optionally, the applicationservice software may be voice dial-up software, and may be instantmessaging software such as WeChat, QQ electronic mail, or a shortmessaging service.

S103. The terminal acquires a voice instruction input by a user, andruns the application service software according to the voiceinstruction. After starting the application service software, theterminal may receive voice input of the user. Accordingly, a recordingdevice in a background starts recording at this time. Optionally, afterstarting the application service software, the terminal may notify, in amanner of vibrating or playing an alert tone, the user that the voiceinstruction can be currently input. After receiving the voiceinstruction input by the user, the terminal runs the application servicesoftware according to the voice instruction input by the user, so as toprovide a corresponding application service for the user. For example,when the user needs to make a call to “XXX”, the user may input “callXXX” by means of voice. In this case, after recording the voiceinstruction, the recording device in the background of the terminaltriggers the voice service software to respond to the voice instructioninput by the user, that is, a speech recognition system in the terminalconverts the received voice instruction into a text instruction, andthen acquires call information (that is, application serviceinformation) according to the text instructions. For example, if thevoice instruction is “call XXX”, the application service informationacquired by the terminal is a number of XXX. After the terminal obtainsthe call information, a quick call system in the terminal starts a callservice.

In the prior art, when a terminal is in a black screen state with arunning AP, and when the terminal needs to provide an applicationservice for a user, application service software is usually started bymeans of voice wake-up, so that the terminal provides a correspondingapplication service. In this case, a recording device in a background ofthe terminal needs to be always in a recording state from the voicewake-up, and after the application service is provided for the user, therecording device in the background is still in the recording state, soas to be ready to receive voice instruction input of the user anytime.Therefore, power consumption of the terminal is relatively large becausethe background performs recording all the time. However, regardless ofwhether a terminal is in a black screen state with a running AP or ablack screen state with a standby AP, in the present disclosure,application service software is started by using event triggerinformation on the terminal, a recording device in a background startsto run only after the application service software is started, so as toreceive a voice instruction of a user, and after the terminal providesan application service for the user, the background stops recording.Therefore, power consumption brought by the recording device in thebackground is reduced. It should be noted that when a terminal is in ablack screen state with a standby AP, and after a user performs atrigger operation on the terminal, the terminal needs to start the AP,and then can acquire event trigger information.

According to the method for quickly starting an application serviceprovided in this embodiment of the present disclosure, a terminalacquires event trigger information, and starts application servicesoftware after determining that the event trigger information meets apreset quick startup condition, so as to provide a correspondingapplication service for a user. According to the method provided in thisembodiment of the present disclosure, application service software isstarted by using event trigger information, so that a background of aterminal starts to perform recording only after the application servicesoftware is started, and background recording is stopped after theterminal provides an application service for a user, preventing arecording device in the background of the terminal from being always ina recording state, and further reducing power consumption of theterminal.

FIG. 2 is a schematic flowchart of Embodiment 2 of a method for quicklystarting an application service according to the present disclosure. Themethod involved in this embodiment is a process in which a call isquickly made on a terminal, that is, the application service software inthe foregoing Embodiment 1 is dial-up application software. As shown inFIG. 2 , the method may include the following steps.

S201. A terminal acquires event trigger information, where the eventtrigger information is used to start dial-up application software. Whena user needs to quickly make a call on the terminal, the user mayperform a related trigger operation on the terminal, so that aprocessing chip inside the terminal can acquire event triggerinformation according to the trigger operation of the user, and reportthe event trigger information to an operating system of the terminal.The event trigger information is used to start the dial-up applicationsoftware, and the dial-up application software may be voice dial-upsoftware. Optionally, the terminal may acquire the event triggerinformation in a screen-on state. Optionally, the terminal may acquirethe event trigger information in a black screen state. For example, theterminal may acquire the event trigger information in a black screenstate with a running AP, may further acquire the event triggerinformation in a black screen state with a standby AP, and may furtheracquire the event trigger information in a black screen state with theterminal having a secure screen lock. This embodiment of the presentdisclosure sets no limitation on a scenario in which the event triggerinformation is acquired.

S202. The terminal starts the dial-up application software afterdetermining that the event trigger information meets a preset quickstartup condition. After acquiring the event trigger information used tostart the dial-up application software, the operating system of theterminal determines a type of the event trigger information, determines,according to the type of the event trigger information, a quick startupcondition corresponding to the event trigger information, and thendetermines whether the event trigger information meets the determinedquick startup condition. Optionally, the quick startup condition may bedetermining whether a time of acquiring the event trigger informationexceeds a preset time threshold, or may be determining whether the typeof the event trigger information matches information preset in theterminal, or may further be determining whether content included in theevent trigger information is the same as information preset in theterminal, or may further be another determining condition. If a resultof the determining is that the event trigger information meets the quickstartup condition, the terminal starts the dial-up application software.

S203. The terminal acquires a voice instruction input by a user, andruns the dial-up application software according to the voiceinstruction. After starting the dial-up application software, theterminal may receive voice input of the user. Accordingly, a recordingdevice in a background starts recording at this time. Optionally, afterstarting the dial-up application software, the terminal may notify, in amanner of vibrating or playing an alert tone, the user that the voiceinstruction can be currently input. After receiving the voiceinstruction input by the user, the terminal runs the dial-up applicationsoftware according to the voice instruction input by the user. Forexample, when the user needs to make a call to “XXX”, the user may input“call XXX” by means of voice. In this case, after recording the voiceinstruction, the recording device in the background of the terminaltriggers the dial-up application software to respond to the voiceinstruction input by the user, that is, a speech recognition system inthe terminal converts the received voice instruction into a textinstruction, and then acquires call information (that is, applicationservice information) according to the text instructions. For example, ifthe voice instruction is “call XXX”, the application service informationacquired by the terminal is a number of XXX. After the terminal obtainsthe call information, a quick call system in the terminal starts a callservice. Optionally, the terminal may receive, in the case of screen-on,the voice instruction input by the user. Optionally, the terminal mayfurther receive, in a black screen state, the voice instruction input bythe user. For example, the terminal may receive, in a black screen statewith a running AP, the voice instruction input by the user, may furtherreceive, in a black screen state with a standby AP, the voiceinstruction input by the user, and may further receive, in a blackscreen state with the terminal having a secure screen lock, the voiceinstruction input by the user. This embodiment of the present disclosuresets no limitation on a scenario in which the voice instruction input bythe user is received.

According to the method for quickly starting an application serviceprovided in this embodiment of the present disclosure, a terminalacquires event trigger information, and starts dial-up applicationsoftware after determining that the event trigger information meets apreset quick startup condition, so as to provide a correspondingapplication service for a user. According to the method provided in thisembodiment of the present disclosure, dial-up application software isstarted by using event trigger information, so that a background of aterminal starts to perform recording only after the dial-up applicationsoftware is started, and background recording is stopped after theterminal provides a dial-up service for a user, preventing a recordingdevice in the background of the terminal from being always in arecording state, and further reducing power consumption of the terminal.

FIG. 3 is a schematic flowchart of Embodiment 3 of a method for quicklystarting an application service according to the present disclosure.This embodiment involves a process in which a user triggers, by using abutton, a terminal to start an application service. As shown in FIG. 3 ,the method may include the following steps.

S301. A terminal receives a button startup event that is input by a userby performing an operation on a physical button. When the user needs toquickly start an application service on the terminal, the user mayperform a button-pressing operation on the terminal, that is, the usermay input the button startup event to the terminal by performing thebutton-pressing operation.

Optionally, the terminal receives the button startup event that is inputby the user by performing an operation on the physical button once, thatis, the button startup event is input by the user to the terminal byperforming one button-pressing operation. For example, it is assumedthat the terminal is a smartphone, the button startup event of the usermay be startup by holding down a physical button of the terminal, suchas startup by holding down a volume down button (Volume−), startup byholding down a volume up button (Volume+), startup by holding down apower button, or startup by holding down a shutter button of a mobilephone camera; may further be startup by holding down a Bluetooth headsetbutton, such as startup by holding down a Bluetooth headset dial key,startup by holding down a Bluetooth headset volume down button, orstartup by holding down a Bluetooth headset volume up button; and mayfurther be startup by holding down a wired headset button, such asstartup by holding down a wired headset volume down button, startup byholding down a wired headset volume up button, or startup by holdingdown a wired headset play button. Performing an operation on a physicalbutton once by the user to input the button startup event is supportedby the terminal, facilitating a user operation. In particular, in ascreen-off or screen locked state of the terminal, supporting input ofthe button startup event by performing one operation improvesmanipulation efficiency.

Optionally, the terminal receives a button startup event that is inputby the user by double-tapping a button or tapping a button.

S302. The terminal acquires the event trigger information according tothe button startup event. It should be noted that when the terminal isin a black screen state with a running AP, the terminal may directlyacquire the event trigger information according to the button startupevent of the user. When the terminal is in a black screen state with astandby AP, after receiving the button startup event of the user, theterminal needs to power on the AP to activate the AP, and then canacquire the event trigger information according to the button startupevent.

S303. The terminal determines whether a trigger time of the buttonstartup event is greater than a preset threshold, and if yes, theterminal starts application service software. When the terminal is inthe black screen state with a running AP, after acquiring the eventtrigger information, the terminal directly performs encapsulation andclassification processing on the event trigger information. When theterminal is in the black screen state with a standby AP, the terminalneeds to perform self-test and recovery on the AP after the AP ispowered on, and the terminal performs encapsulation and classificationprocessing on the acquired event trigger information only after it isdetected that a status of the AP is normal.

Encapsulation and classification processing performed by the terminal onthe event trigger information is determining a type of the event triggerinformation by the terminal. When the terminal determines that the typeof the event trigger information is a button startup event, the terminaldetermines, according to the type of the event trigger information, thata quick startup condition corresponding to the event trigger informationis whether a trigger time of the button startup event is greater thanthe preset threshold. For example, it is determined whether a time ofpressing a button by the user is greater than a preset threshold. If thetime of pressing a button by the user is greater than the presetthreshold, the terminal starts the application service software.Optionally, when the user presses a different button, it indicates thatthe user needs to start different application service software. Forexample, if the user currently wants to start a voice service, when theuser holds down a volume down button on the terminal, the event triggerinformation obtained by the terminal is information about voice servicesoftware. If the user currently wants to start a short messagingservice, when the user holds down a volume up button on the terminal,the event trigger information obtained by the terminal is informationabout short messaging service software. That is, a button-pressingoperation performed by the user, event trigger information acquired bythe terminal according to the button-pressing operation performed by theuser, and an application service software that needs to be started arecorresponding to one another.

S304. The terminal receives the voice instruction input by the user.After starting the application service software, the terminal mayreceive voice input of the user. Accordingly, a recording device in abackground starts recording at this time. Optionally, after starting theapplication service software, the terminal may notify, in a manner ofvibrating or playing an alert tone, the user that the voice instructioncan be currently input.

S305. The terminal converts the voice instruction into a textinstruction, so as to acquire application service information. Afterreceiving the voice instruction input by the user, the terminal convertsthe voice instruction into the text instruction according to the voiceinstruction input by the user, so as to acquire the application serviceinformation related to the voice instruction.

S306. The terminal provides the application service according to theapplication service information. In an implementation manner of thisembodiment of the present disclosure, the terminal may perform anoperation of quickly making a call. Optionally, the terminal is a mobilephone. Optionally, the terminal is in a black screen state with arunning AP. Optionally, the terminal is in a screen locked state.

The user starts application service software by using a button on thesmartphone, that is, the user performs one button-pressing operation onthe smartphone, for example, holds down a volume down button, so as toinput a button startup event to the smartphone. Related hardware of thesmartphone responds to the button startup event of the user, which isrepresented as converting a button event of the user into event triggerinformation that includes information such as a signal and data, andreporting the event trigger information to an operating system of thesmartphone. After receiving the event trigger information, the operatingsystem of the smartphone performs encapsulation and classificationprocessing on the event trigger information, that is, determines a quickstartup condition corresponding to the event trigger information (thatis, whether a time of holding down a button by the user is greater thana preset threshold), and starts voice service software after determiningthat the time of holding down a button by the user is greater than thepreset threshold.

A device in a background of the smartphone starts to perform recordingonly after the smartphone starts the voice service software, so as toreceive voice instruction input of the user. In this case, the voiceservice software may notify, in a manner of playing an alert tone orvibrating, the user that a voice instruction for making a call, such as“redial”, “call XXX”, or “make a call to XXX”, can be input, where “XXX”is a name of a contact. A speech recognition system in the smartphoneconverts the received voice instruction into a text instruction, andthen acquires application service information (that is, callinformation) according to the text instructions. For example, if thevoice instruction is “redial”, the application service informationfinally acquired by the smartphone is a call number last time; if thevoice instruction is “call XXX”, the application service informationfinally acquired by the smartphone is a number of XXX.

After the smartphone obtains the application service information, aquick call system of the smartphone starts a call service. In this case,the smartphone automatically lights up a screen, automatically hides asecure-lock unlocking interface to display a call interface, and remindsthe user of call information, such as a called party or a call number.If the call information is incorrect, the user may directly abort a callprocess by means of voice or by tapping a call hang-up button. In anentire procedure for starting a voice service, the user requires onlyone time of button pressing and one time of voice instruction input.

After the user finishes the call, that is, the voice service provided bythe smartphone for the user is complete, the device in the background ofthe smartphone stops recording, and the smartphone still displays thesecure-lock unlocking interface. During a period of calling andconversation, personal information of the user, such as address bookdata and personal information that is stored on the mobile phone, isstill protected by a secure lock.

According to the method for quickly starting an application serviceprovided in this embodiment of the present disclosure, a user inputs abutton startup event to a terminal, so that the terminal acquires eventtrigger information according to the button startup event, and startsapplication service software after determining that the event triggerinformation meets a preset quick startup condition, so as to provide anapplication service for the user. According to the method provided inthis embodiment of the present disclosure, application service softwareis started by using event trigger information, so that a background of aterminal starts to perform recording only after the application servicesoftware is started, and background recording is stopped after theterminal provides an application service for a user, preventing arecording device in the background of the terminal from being always ina recording state, and further reducing power consumption of theterminal. In addition, according to the method provided in thisembodiment of the present disclosure, a user does not need to light up ascreen or unlock a screen, but only needs to perform one button-pressingoperation and input one voice instruction, so that a terminal canprovide a corresponding application service, which is easy to operate,thereby improving manipulation efficiency and enhancing user experience.

FIG. 4 is a schematic flowchart of Embodiment 4 of a method for quicklystarting an application service according to the present disclosure. Themethod involved in this embodiment is a process in which a user startsapplication service software on a terminal by using a sensor startupevent, so that the terminal provides a corresponding application servicefor the user. As shown in FIG. 4 , the method may include the followingsteps.

S401. A terminal receives a sensor startup event input by a user. Whenthe user needs to quickly start an application service on the terminal,the user may perform a sensing operation on the terminal, and input thesensor startup event to the terminal by using the sensing operation,that is, the terminal may acquire the sensor startup event by sensing agesture of the user. For example, it is assumed that the terminal is asmartphone, the sensor startup event of the user may be that the userholds an earpiece near an ear of the user, may further be another eventthat the user quickly swings the smartphone and then stops, and thelike.

S402. The terminal acquires event trigger information according to thesensor startup event. It should be noted that when the terminal is in ablack screen state with a running AP, the terminal may directly acquirethe event trigger information according to the sensor startup event ofthe user. When the terminal is in a black screen state with a standbyAP, after receiving the sensor startup event of the user, the terminalneeds to power on the AP to activate the AP, and then can acquire theevent trigger information according to the sensor startup event.Optionally, the sensor startup event input by the user may further becombined with the button startup event in the foregoing Embodiment 2, sothat the terminal acquires the event trigger information.

S403. The terminal determines whether the event trigger informationmatches event information in a preset event information set of theterminal, and if the event trigger information matches the eventinformation in the preset event information set of the terminal, theterminal starts the application service software. When the terminal isin the black screen state with a running AP, after acquiring the eventtrigger information, the terminal directly performs encapsulation andclassification processing on the event trigger information. When theterminal is in the black screen state with a standby AP, the terminalneeds to perform self-test recovery on the AP after the AP is poweredon, and the terminal performs encapsulation and classificationprocessing on the acquired event trigger information only after it isdetected that a status of the AP is normal.

Encapsulation and classification processing performed by the terminal onthe event trigger information is actually determining a type of theevent trigger information by the terminal. When the terminal determinesthat the type of the event trigger information is a sensor startupevent, the terminal determines, according to the type of the eventtrigger information, that a quick startup condition corresponding to theevent trigger information is whether the event trigger informationmatches the event information in the preset event information set (thepreset event information set of the terminal includes multiple pieces ofevent information). Optionally, the preset information set may be storedin a form of an entry, or may also be stored in a form of an informationbase, which is not limited in this embodiment of the present disclosure.If the event trigger information matches the event information in thepreset event information set, the terminal starts the applicationservice software. Optionally, when the user inputs a different sensorstartup event to the terminal, it indicates that the user needs to startdifferent application service software. For example, if the usercurrently wants to start a voice service, the user holds the earpiece ofthe mobile phone near the ear, and the event trigger informationobtained by the terminal according to the sensor startup event isinformation about voice service software. If the user currently wants tostart a short messaging service, the user swings the mobile phone, andthe event trigger information obtained by the terminal according to thesensor startup event is information about short messaging servicesoftware. That is, a sensing operation performed by the user (that is, asensor startup event input by the user), event trigger informationacquired by the terminal according to the sensing operation performed bythe user, and an application service software that needs to be startedare corresponding to one another.

S404. The terminal receives the voice instruction input by the user.After starting the application service software, the terminal mayreceive voice input of the user. Accordingly, a recording device in abackground starts recording at this time. Optionally, after starting theapplication service software, the terminal may notify, in a manner ofvibrating or playing an alert tone, the user that the voice instructioncan be currently input.

S405. The terminal converts the voice instruction into a textinstruction, so as to acquire application service information. Afterreceiving the voice instruction input by the user, the terminal convertsthe voice instruction into the text instruction according to the voiceinstruction input by the user, so as to acquire the application serviceinformation related to the voice instruction.

S406. The terminal provides the application service according to theapplication service information. In an implementation manner of thisembodiment of the present disclosure, the terminal may perform anoperation of quickly making a call. Optionally, the terminal is a mobilephone. Optionally, the terminal is in a black screen state with arunning AP. Optionally, the terminal is in a screen locked state.

The user starts application service software by performing a sensingoperation on the smartphone. That is, the user performs one sensingoperation on the smartphone. For example, the user holds an earpiece ofthe smartphone near the ear, so as to input a sensor startup event tothe smartphone. Related hardware of the smartphone responds to thesensor startup event of the user, that is, the smartphone first powerson the AP to activate the AP, and then converts the sensor startup eventof the user into event trigger information that includes informationsuch as a signal and data, and reports the event trigger information toan operating system of the smartphone. After receiving the event triggerinformation, the operating system of the smartphone first performsself-test recovery on the AP, and after a status of the AP is normal,encapsulation and classification processing is performed on the eventtrigger information, that is, a quick startup condition corresponding tothe event trigger information (that is, whether the event triggerinformation matches event information in a preset event information setof the smartphone) is determined, and after it is determined that theevent trigger information matches the event information in the presetevent information set of the smartphone, voice service software isstarted.

A device in a background of the smartphone starts to perform recordingonly after the smartphone starts the voice service software, so as toreceive voice instruction input of the user. In this case, the voiceservice software may notify, in a manner of playing an alert tone orvibrating, the user that a voice instruction for making a call, such as“redial”, “call XXX”, or “make a call to XXX”, can be input, where “XXX”is a name of a contact. A speech recognition system in the smartphoneconverts the received voice instruction into a text instruction, andthen acquires application service information (that is, callinformation) according to the text instructions. For example, if thevoice instruction is “redial”, the application service informationfinally acquired by the smartphone is a call number last time; if thevoice instruction is “call XXX”, the application service informationfinally acquired by the smartphone is a number of XXX.

After the smartphone obtains the application service information, aquick call system of the smartphone starts a call service. In this case,the smartphone automatically lights up a screen, automatically hides asecure-lock unlocking interface to display a call interface, and remindsthe user of call information, such as a called party or a call number.If the call information is incorrect, the user may directly abort a callprocess by means of voice or by tapping a call hang-up button. In anentire procedure for starting a voice service, the user requires onlyone sensing operation and one time of voice instruction input.

After the user finishes the call, that is, the voice service provided bythe smartphone for the user is complete, the device in the background ofthe terminal stops recording, and the smartphone still displays thesecure-lock unlocking interface. During a period of calling andconversation, personal information of the user, such as address bookdata and personal information that is stored on the mobile phone, isstill protected by a secure lock.
